A real-time view of the GB electricity system has been provided by Elexon, the company responsible for the GB electricity balancing and settlements infrastructure.  This page shows demand, margin, generation mix and a variety of other data.

It is also possible to track the activities of large power stations, or “Balancing Mechanism Units” (BMUs).  To use this page, you will need National Grid's list of licensed power stations.

Utilisation of Short Term Operating Reserve from sources other than large power stations, including Flexitricity, can be viewed on the STOR non-BM instructed volumes page.  Please note that the data shown here are in MWh total instructed in each half-hour.  The actual MW generation or load reduction can be estimated by doubling the MWh figure.
